5. Summary of results

The comparison of the results from the*Code_Aster* and those obtained numerically by the code FEAP of Professor Taylor from Berkeley are satisfactory (the maximum difference is \(\text{2.18\%}\) on the constraints).

The objective of the modeling is to test the stability of the law of behavior using the joint elements already existing in the Code_Aster: we can consider that the implementation of the law is correct. However, since the maximum strength of the bond between steel reinforcements and concrete is achieved beyond the scope of small deformations, care must be taken when choosing time increments, especially when JOINT_BA is used in combination with other non-linear laws of behavior (law MAZARS, for example).
